SHEEI 1 BF 2 INVENTOR Seorcy A. Watson ATTORNEYS P'A'TENTEMN 10 I972 SHEET 2 OF 2 INVENTOR Seorcy A. Watson ATTORNE YS l TWO-PART HINGE WITH INTEGRAL PIN SUMMARY OF THE INVENTION A novel hinge of only two pieces which can be more economically manufactured, such as by extrusion, than conventional three piece hinges and which can be made integral with door frame and joint members. The leaves of the hinge have complementary semicylindrical segments adapted to nest when said hinge is in closed position as well as during initial opening and final closing movements of the hinge. A coextensive hinge pin is made integral with the outer segment during initial closing and final opening movements of the hinge. The structure of the hinge permits 180 movement thereof and any configuration of its external segment. Also, there is minimum surficial contact between the leaves of the hinge without sacrificing adequate rigidity.

FIG. 6 is an enlarged view similar to FIG. 4.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings, the numeral 1 designates a hinge embodying the principles of the invention and comprising a pair of hinge members or leaves 2 and 3 disposed in substantially parallel relationship. The larger or outer hinge leaf 2 may be made integral with or otherwise secured to an angular jamb member 4 which may be of the extruded type, while the smaller or inner hinge leaf 3 may be made integral with or otherwise secured to a U-shaped closure or door frame member 5 closed. It is noted that the free or outer longitudinal margins of each of the segments is open or spaced from of the same type. Although illustrated, the details of construction of the jamb and door or closure members are merely typical and form no part of this invention. For purposes of illustration only, portions of a wall 6 and a door closure 7 are shown in broken lines.

It is noted that the hinge may be of any length, such as a few inches or coextensive with the contiguous margins of the door or closure and the jamb members and, preferably, has coextensive elements or parts. Also, it is pointed out that the hinge is particularly useful for mounting the swinging doors and other closures of-r'no: bile homes and recreational vehicles. A coextensive flange 8 may be made integral with the outer leaf, while the inner leaf may have a similar integral flange 9 to facilitate mounting of the leaves on the members. Even though illustrated as having three offset portions, it is readily apparent that the flange 9 may be exactly right angular.

The larger or outer leaf 2 of the hinge has an arcuate portion or substantially semicylindrical segment 10 for nesting engagement with a complementary arcuate segment or semicylindrical portion 11 of the smaller or inner hinge leaf 3 (FIGS. 2, 4 and 6) when the door is the remainder of said segments and that at least the contiguous portion of each of the flaiiges 8 and 9 extends radially of its integral segment. The outer segment 10 is of greater radius than the inner segment 11 and has an arcuate internal face 12 concentric with and complementary to the external face 15 of said inner segment. Although the external face 14 may be arcuate as shown, this is not essential except from an esthetic viewpoint; however, thearcuateness a'nd concentricity of the internal face 13 of the 'intemal segment is essential for guiding the pivotal movement of the inner hinge leaf relative to the outer hinge leaf.

A coextensive hinge or pivot pin 17 is disposed longitudinally and concentrically of the internal segment 11 and is integrally connected to the free end of said segment by an integral, angular, radially-extending web 19. The latter has its outer section or leg 21 stepped or offset transversely outward of its inner section or leg 23 toward, in the closed position of the hinge, an overlying angular web 16 made integral with and extending radially inward from the free end of the outer segment 10. As best shown in FIGS. 5 and 6, the overlying web 16 includes an inner radial leg or section 18 connected by an intermediate transverse section or leg 20 to an outer substantially radial leg or section 22 in outward offset or stepped relationship.

An inner arcuate face 24, concentric with the hinge pin 17, isprovided on the outer extremity of the leg 22 for coaction with said pin, and said leg has a flange 26 projecting radially outward therefrom in coacting relation to the internal arcuate face 13 of the segment 11 when the hinge is open as shown in FIGS. 1, 3 and 5. If desired for economy of manufacture, the entire extremity of this leg may be arcuate in plan. A lip 28 projects transversely outward from the outer end portion of the flange 26 to provide an amplified face 30 which may be arcuate and which is concentric with the segment face 13. The intermediate leg 20 has an outer portion 32 extending outwardly of the leg 22 in substantially parallel relationv to its flange for coaction therewith. Preferably, an arcuate external face 34 is formed on the leg outer portion 32 and is concentric with the internal face .of :the segment. 11. In order to prevent axial or longitudinal movement of the hinge leaves 2 and 3 relative to each other, at least one angular bracket 25 is suitably secured to the jamb member 3 adjacent the outer segment 10 and has a horizontal or transverse substantially circular arm 27 extending through aligned horizontal or transverse slots 29 in the segments 10 and 1 1.

When the closure or door is closed as shown in FIGS. 2, 4 and 6, the inner leaf segment 11 is nested within the outer leaf segment 10 with the faces 12 and 15 of said segments in close proximity, and with the web 19 and its sections 21 and 23 of the inner leaf 3 contiguous the legs 18 and 22 as well as the leg 20 0f the web 16 of the outer leaf 2. Upon initial opening and final closing of the door, the inner segment rotates within the outer segment with the external face 15 of said inner segment sliding over the internal face 12 of said outer segment. The hinge pin 17 of the inner leaf turns within the arcuate face 24 of the outer leg 22 of the web 16 of the outer leaf to the open position shownin FIGS. 1, 3 and 5. During approximately the last half of this opening movement as well as during approximately the first half of the closing movement of the hinge leaves, the internal face 13 of the inner segment slides over the external arcuate face 30 of the lip 28 of the flange 26 of the outer web leg 22 and the external arcuate face 34 of the outer portion 32 of the intermediate web leg to guide such rotational movement in coaction with the hinge pin.

lt is noted that the structure of the hinge permits opening of the door to 180 from its closed position which is particularly advantageous when the door is on a side of a vehicle. Since the hinge pin is integral with the inner leaf of the hinge, fabrication by extrusion is made possible and is more economical than conventional manufacture. Manifestly, the hinge leaves may be made integral with metal closure or door and jamb members and, when coextensive with said members,

the hinge may be of extremely light-weight construction. Of course, the coextensiveness of the hinge is highly desirable from an esthetic standpoint.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
